I probably shouldn't be but oh well. As a back story, Summer was 4 when I got her and since then she's never really played with anything. She really seems to have issues with things in her mouth that she doesn't like. I've been working off and on to shape her to play and mouth with things. Today she shredded some paper towels I was holding. Ran up and bit them and started shaking them. Then I held up another and she ran up and grabbed it and tore it up. She's so funny and still so gentle. But tail wagging, having a good time and shredding (albeit gently) away. I know, I know... not a big deal. But she's never ever played with anything before. My clicking for her biting and grabbing things I have is definitely working, slowly but surely. So yes, a happy post because my dog can now do what so many people try to get their dogs not to do.
